Re: PIX 501 displaying Error Message


It looks like you rebooted your Pix. I would monitor connections and xlates to see if you are exhausting resources. Is this the first time this has happened? How long has this Pix been in production?

I see you are running 6.3.3, perhaps CSCec45748 - New DNS conns reset the idle timer of previous DNS conns. is a suspect???

Hope this helps! If so, please rate.
